Infiltrator will be release for iOS devices and it's pretty much a third-person shooter that will involve an enemy Cerberus base or something like that.
The fun part?
Players will receive rewards by collection evidence of Cerberus's crimes. AND the actions made on the game will affect Mass Effect 3, be it by unlocked weapons or whatever.
-All that matters-
Mass Effect 3 will be released 9/3 and Infiltrator is said to be released almost at the same time. Fun fun.
